What's new on the QTC+?Matte Black PCB with Gold pads
Reduced component count for RGB LEDs
Simpler Anode Drivers, with socketed Optoisolators, for easier assembly and troubleshooting
Double dot colon neons, with many more modes
Support for our XTERNA Wireless Time and Temperature Transmitter

Previously, a failed tube always meant a treacherous operation to delicately remove the tube whilst trying to preserve all traces intact. Whilst this was certainly possible, It was never easy, and made it uncomfortable to give a Nixe Clock as a gift in case a tube ever failed. With the QTC system (‘Quick Tube Change’), each tube is soldered only to its own mini ‘tube cell’ PCB. A tube can be changed in minutes with no danger to the main PCB. The small addition in cost is dwarfed by the huge advantage this gives. A single main board is capable of driving tens of different types of solder-in Nixie Tube. You can even completely change the tube type of your clock by installing new tube cells and tubes.

Here is the clock after assembly - ready to mount in the included case.

Drive Mode
The former K155ID1 / 74141 nixie driver IC is now replaced by a modern HV5812 High Voltage Driver IC by Supertex. With 20 outputs, it is able to drive the six Nixie Tubes in a very comfortable 3X2 multiplex.

The fully assembled clock, in case. Everything is included!

GPS Time Synchronisation
Included is a GPS Time Synchronisation Receiver, which automatically receives time and date from GPS satellites. Please note, the GPS needs to be within 2m / 6ft of a window.

12V Power Adapter
A high quality power adapter for your country is included, with a long 1.8m / 6ft cable.
